Geophysical Anomalies Reveal New Copper Targets at Rae Project

White Cliff Minerals Limited (“the Company”) is pleased to announce further results of the first project scale geophysical survey at the Rae Copper Project (“Rae” or “the Project”), Nunavut, Canada.

• The Stark target, a newly identified anomaly sits along a known copper conduit, the Herb Dixon Fault. The Herb Dixon Fault forms the western boundary of the HULK sedimentary targets and extends south, to the Company’s Vision District where rock chip assays included 64.02% (F005965), 62.02% (F005966), 55.01% (F005977) and 50.48% (F005959) copper
• The Stark target presents as a highly conductive signature over more than 14km strike length and up to 2.2km wide that is coincident within a well-defined structure
• A further western target at Hulk, West - Target D (Cliff) presents another target for large scale vein hosted systems with a strong conductivity anomaly, constrained within a major structure over 5.7 km strike length and up to 1 km wide which crosses the basalt-sediment contact
• This new target at Hulk further increases the interpreted dimensions of the Hulk target to 23km by 10.5km
• Within the Thor District at the Halo target, high grade samples over > 800m strike length including results up to 54.02% Cu (F005921) a conductivity response spanning 2.7km strike length has expanded the initial high grade target, inferring a significant extension to the mineralisation observed on surface
• Field truthing at Halo identified significant quantities of copper mineralisation embedded within basalts and sediments at surface. This field observation, now corroborated by the Mobile MT electromagnetic survey results, offers scope for further discoveries at other conductivity anomalies within the Thor District
• The ongoing review of the MobileMT geophysical data, in parallel with the integration of magnetic and conductivity datasets with assay results from the maiden campaign will generate an evolving pipeline of new targets. Follow up ground truthing is being planned to operate in parallel with the maiden drilling campaign at Rae where mobilizing works are planned for Q1 of 2025

“These airborne geophysical results have revealed kilometre scale conductive signals which seem to be constrained to the interpreted dimensions and structures of the regional fault networks. It is this constraint that provides us with additional confidence in the geophysical responses, as these conductive anomalies, in those shapes are what we were hoping to see.

These large scale vein system targets are unique in that they provide super high grade copper targets and a major conduit of hydrothermal copper fluids; seeing the entire Herb Dixon fault in this regard and its connection into the sedimentary structures at Hulk is very exciting.

Being able to link high grade surface showings with extensions into the sub surface, like the Halo target, is significant given the consistent high grades returned during the summer sampling program. We have now identified, nearby, conductive sub surface signatures, offering up scope for further discoveries in the Thor District.

This ongoing generation of targets will feed into the 2025 ground sampling program (ground truthing geophysical anomalies) that will run in tandem with our maiden drilling campaign at the Project.”
